بوم شناسي
; آب شيرين موجوداتی که در محدوده وسیعی از آبهای آزاد از نزدیک بستر و یا روی کف بستر، در قسمت های میان آبی تا سطح آب و در برخی گونه ها با قابلیت پرواز، زندگی و تغذیه می کنند., usually 1 - 3 m (Ref. 35835). Tropical
Africa: Lake Tana, Ethiopia (Ref. 35835, 128753). Also Didessa River in Ethiopia, but occurrences outside Lake Tana would suggest dispersion (Ref. 35835).

خارهاي باله پشتي (کل) : 0; شعاع نرم باله پشتي (کل) : 12 - 13; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 8. Head width less than 1.8 times in head length; head length more than 1.3 times in body depth; body depth less than 3.6 times in standard length; eye diameter more than 1.3 times in interorbital width; dark green; often with an extended, soft abdomen.
Occurs over muddy, sandy and rocky substrates all over the lake, preferably in water of no more than 3 m depth. Is a real macrophytivore: specimens smaller than 15 cm feed mainly on zooplankton and insect larvae; macrophytes increase in importance with size and finally make up most of the diet (Ref. 35835).
